Application med December 26, 1908. Serial No. 469,251.
To all whom 'it may concern: i
Be it known that I, JOHN CLARK UDALL, a citizen of the United States, and a resident of Sound Beachfn the county of Ez'iirieldl and State of Connecticut, have invented'cer tain new and useful Improvements in the Process of Making Stencils, of which the following is a specification.
My invention relates to the process of making stencils for applying artistic impressions or pictures to the surfaces of wood, metal, fabrics, etc., the stencil being capable of being made in the likeness of natural objects.
Thel object of the invention, among other things, is to so construct or fabricate the stencil that correlated dots or Ispots on the netting, as well as the narrow lines, and the margins of the solid portions, will not only prevent the paint or other coloring material from being spread upon the surface receiving the impression, but will revent the coloring matter from spreading eneath or back of the said' dots or spots, or beneath or back of the narrow lines on the stencil or back of the edges of the margins outlining the subject of the stencil. l
In the accom anying drawings to which reference is ma e, and which form a part of this specification,-Figure l is a plan. View of a portion of a stencil, made in accordance with my invention. Fig. 2 is a sectional elevation of a'plate, having the netting applied thereto. Fig. 3 is a back view of the plate and netting. Fig. 4 shows a modification of the plate- In the accompanying drawings, 2 desig-- nates the body of the stencil, composed of netting of a suitable mesh, preferably French lawn or organdy.
In making the stencil the bod 2 of netting is applied tothe surface o a late 3, preferably a zinc late, perfectly at and polished on the sur ace' to which the net-ting is applied. The netting is folded over the edges of the plate and held fast, preferably by sticking it to the b`ack of the plate, as
shown at 4, by means of paste or other ad-I hesive material. The netting is drawn snug and fla-t on the plate, and drawn in two directions, at right angles, so that the strands are drawn taut and are held in that condition, in close contact with the plate. Thus secured to the plate, the netting and the plate itself are` coated withsensitized glue,
sensitized gelatin, or other sensitized'adhe sive material, which, when exposed to light, will take a photographic print.
I prefer to apply three coats of the sensitized material to the netting, and to the surface of the plate, and to bake each coating before the other is applied, care being taken not to expose the plate to the action of light,
at least after the first coat has been put on and baked. The netting and plate now befingproperly coated and dried, I take a transparency, preferably a glass photo graphic negative, on which has been taken, through a screen, or a plate of lined glass, the picture of the person, object or thing desired to be the subjectto be reproduced by the use of the stencil, and apply thereto the coated netting and plate in a printing frame,
kand print the sensitized netting and plate by exposure to sunlight or the action of the actinic rays of artificial. light in the manner well known as sun print1ng in the art of photography. do not limit myself to the use of a photographic transparency, but if such a half-tone photographic negative be used, I refer to place it in the printing frame wlth the film side up, so that the film will make a perfect contact with the sensitized material on the netting and plate. In printing, those portions of the sensitized material on the netting and plate, 'which are acted u on by the light., are rendered insoluble in water, while those portions .not exposed to the light remain soluble in water, and both of said portions after exposure still remain at all parts closely adherent to the dat and polished surface of the plate, and a sharp demarcation between the insoluble and the soluble portions of the sensitized material is produced by the action of the rays of light. After exposure to the light, the plate 3, the netting and `the coating of sensitized material are immediately washed in water, preferably by a stream of water directed upon the same. This wash-` ing dissolves and vcarries away the soluble portions ofthe sensitized material from the netting and from the plate, leaving the strands of the netting clean and exposed,
but still taut, and leaves the insoluble portions still in contact with and adhering to are swollen and rendered soft and quite easily disturbed at their outer surfaces'only,

I `4In order to'ifacilitate the removal of the. netting-.and sensitizedniaterial from the plate, prefer some cases to coat it with' a substance towhich glue will not adhere as tenaciously as it does to the plate itself, and 4forthisg purpose I prefer to employv athin Alayer-,791iori-gall, and. I prefer this because- 4it dries/guickly and whenA dr vhand an dY makes a very smooth surface an is transparent and not affected by heat..;
I do not limit myselfv to the use of a metal4 'i plate, ,asa- :plate of glass vor other material mightbensed, but'I refer a polished metal plate', asit will ,no tj reak or warp, audits .polished surface has a reflective influence during the yexposure forprinting which tendstogsharpen the' lines of demarcation between those parts of thesensitized material which are rendered insoluble andthose which rremain soluble. l
